Swirl flaps are small butterfly valves located in the intake manifold of many diesel engines, particularly in vehicles like BMW, Mercedes, Audi, Vauxhall, and other popular makes. They are designed to improve fuel efficiency and reduce emissions at low engine speeds by creating a swirling motion in the air-fuel mixture.
However, over time, swirl flaps can become clogged with carbon deposits or even break off, potentially causing serious engine damage, reduced performance, and expensive repair bills. That’s why many vehicle owners in Little Venice opt for a swirl flap delete service to remove them permanently.

Swirl flaps are designed to improve fuel combustion at low engine speeds by creating a swirl effect in the air intake. However, they often cause more harm than good – especially as your engine ages.
Common swirl flap issues include:
• Carbon build-up in the intake manifold
• Broken or detached swirl flaps entering the engine (can cause catastrophic damage)
• Poor engine performance and turbo lag
• Excessive black smoke and EGR faults
• Increased fuel consumption
• Engine warning lights and limp mode
• Inconsistent idle or stalling
These problems are especially common in BMW, Mercedes, Audi, Vauxhall, and Ford diesel models.
If your vehicle has swirl flap issues, your diagnostic scanner or dashboard may show some of these frequent fault codes:
BMW / MINI:
• P2004 – Intake Manifold Runner Control Stuck Open
• P2008 – Intake Manifold Runner Control Circuit/Open
• P2006 – Intake Manifold Runner Control Stuck Closed
• 2A67, 2A6B, 2A6C – Swirl flap actuator faults
Mercedes CDI:
• P2015 – Intake Manifold Runner Position Sensor/Switch Range/Performance
• P2004 – Intake Manifold Runner Stuck Open
• P2006 – Intake Manifold Runner Stuck Closed
Vauxhall / Opel:
• P2279 – Intake Air System Leak
• P1125 – Swirl Flap Stuck / Malfunction
• P1112 – Swirl Flap Actuator Circuit
These codes often lead to MOT failures, reduced drivability, and further intake system complications.
Our solution includes:
• Physical swirl flap removal
• Swirl flap blanking kit supplied and fitted (aluminium blanks or delete kits, depending on model)
• ECU reprogramming via custom remap to disable swirl flap operation in software and eliminate related fault codes
• Optional EGR delete/remap available for full intake optimisation
Once removed and reprogrammed, your vehicle will enjoy:
• Improved throttle response and airflow
• No more swirl flap-related fault codes
• Better reliability and fuel economy
• Reduced carbon deposits inside the intake manifold
• Permanent solution – no more warning lights or expensive intake manifold replacements

Swirl flaps are commonly found in the intake manifolds of many diesel engines. Over time, they can become clogged or even break, leading to engine warning lights, poor performance, or costly engine damage. If you drive one of the vehicles listed below, you may be at risk.
Common BMW models affected include the 1 Series (118d, 120d), 3 Series (320d, 330d – E46, E90), 5 Series (520d, 530d – E39, E60), as well as diesel X3 and X5 models. BMW diesel engines, especially those using the M47 and M57 engines, are well known for swirl flap failures. Many owners choose to remove them as a preventative upgrade to avoid engine damage.
Swirl flap issues are also common in Mercedes-Benz diesel models such as the C-Class (C220 CDI, C270 CDI), E-Class (E220 CDI, E270 CDI, E320 CDI), and ML and S-Class diesels. These engines are prone to swirl motor and manifold actuator faults, making swirl flap removal a reliable long-term solution.
Vauxhall and Opel models like the Astra, Zafira, Vectra, and Insignia with 1.9 CDTi and 2.0 CDTi engines often suffer from carbon build-up and swirl flap failure. Symptoms can include black smoke, rough idling, and a loss of power. Deleting the swirl flaps helps restore proper airflow and engine efficiency.
Vehicles within the VAG group — including Audi A3, A4, and A6 (TDI models), VW Golf, Passat, and Touran (1.9 & 2.0 TDI), and Skoda or SEAT TDI models — often develop issues with clogged intake manifolds and faulty swirl actuators. Swirl flap removal in these models is a highly effective fix.
Ford models such as the Mondeo, Galaxy, and S-Max with TDCi engines, as well as Land Rover Freelander 2 and Evoque (TD4, SD4), and Jaguar XF and X-Type diesels, also experience swirl flap wear and actuator failure, especially as mileage increases. Removing swirl flaps helps avoid performance problems and future repair costs.
